IMPROVED METHOD OF HANGING BELLS.

' '.ne Schedule referred to in these Letters Patent and making part of the same.

To all lwhom it may con-cern Be it known that I, GILBERT EGUIILLON, of Paris, in the Empire of France, have invented a new and improved Mode of Suspending Bells by Means of Oscillating Levers; and l do hereby declare that the following is a fnll and exact description thereof, reference being had to the accompanying drawings, and to the-letters of reference marked thereon.

This invention consists in suspending bells by 'means of three or six oscillating levers, which are represented in the accompanying drawings.

Figure 1 shows the position they occupy when the bell is in repose.

Figure 2 shows their position when the bell has reached its maximum of elevation..

The three levers are indicated by the letters D G H, F I J, E K L, and are placed or arranged on the 'pivot or axis of the bell O, which pivot touches each of them at a -single point, m n rc, as shown in lig. l. In fig. 2, it appears to touch them at several points; but this is when it has reached the end of its course.

In the drawings, ligs. 1 and 2, no frame is shown, the dotted lines A B, A C, B C serving to illustrate the plan in which the fulcra of the levers work. The points A B C appear isolated from the respective levers, because the latter are only partly shown. The dotted vlines A E, B D, C E mark the continuation of the levers, the reason of only showing which in part in the two first drawings is, that I do not confine myself to any particular form, either for their tenninaf ltion, or for their support, as it is immaterial to my system; but,in Figures 3 and 4, Ihave shown the system complete, and will mention them hereafter.

The length of the levers would be regulated according to the weight and dimensions of the bell; for in stance, a certainlength of lever being determined, it should be taken as a radius for describing the curve of the apertures on which the pivot turns. Otherwise,

' the play of the` levers will be impeded. The levers the levers will only be mentioned by a single letterthat of their point of suspension-thus: the letter A designates the lever A F I J the letter B, that of the lever B D G H; the letter O, that C E K L.

IVhen the bell is at rest, it is supported, at the point x, by the lever A, which alone sustains it. This lever oscillates vertically when the bell is inmotion.

WVhen the bell turns on its axis from left to right, it acquires a centrifugal force, which tends to throw it violently in the latter direction. Another lever is, therefore, necessary, to resist this action, which is effected by the lever C.

`llhe force of translation to the right acts onthe lever-at the point n. In the same manner, the weight of the bell, when at rest, acts on the level A, at the point Bnt, on the other hand, when the bell moves yfrom right to left, the lever B acts the same part as 'n as on the lever B at the Ypoint m, according as its backward andforward movement is effected fromleft to right, or from right to lef@ In order to comprehend in what manner the oscillation ofthe levers, under the action of the pivot in rotating, is effected, it will be necessary to compare the rigs. 1 and 2 of the drawings.

Fig. 1 represents the levers at rest. `The pivot o then acts on the centre of thecurve or opening therein, at the points m n x. ,y On examining the iig. 2, the same points are represented, but they are no longer the points of action of the' pivot o. resenting the levers when the -bell has reached its maximum elevation, the pivot acts only at the points m n x', in such wise that the bell, moving from left to right, has leftA the perpendicular. The pivot has changed its points of contact on the curves m m, n u', :t x', till it comes to act on the points m' 'a' x', when the bell retraces its steps, and regains the perpendicular position. The pivot, imparting' to the curves a backward and forward motion, runs on them the same course it has already run without changing its centre of action and, when" the bell again leaves the perpendicular, to move to the left, the pivot passes over the second part of the curves, without displacing its centre of action, in the same manner that it has passed over the first part. This latter movement is not shown in the drawings, as it is the same as the first, and produced in the same manner.

The pivot imparts to the lever the different motionsl of right or left, according as the points of its circumference, with which 4the levers are in contact, go from right to left, or from left to right.

The pivot turns on the curves wit-hout sliding; and it is in turning without losing its centre of motion that it'ilnparts to the levers a backward and forward motion.

The disposition or arrangement of the levers is an essential feature in my invention, as the pivot is acted on by the openingsr in the levers in the same manuel' as, but in place of gear-wheels, and the points of suspension, being chosen, at will, on the whole length of the frame, in a pla-ne perpendicular to the axis of the bell, admits of the levers being any desired length, giving increased power of action, and a regular and even motion. g

\ By reason of this facility of havingthe fulcra of the levers at any desired point, the necessity of employ ingaframe is obviated. This will be more clearly understood on reference to g. 1.

In lieu of having the point-s A B C attached to the This gure repi framelin a plane perpendicular to the axis of the bell, the point A mayxbe attached to a cross-beam or other solid object placed above the belfry, and resting on its walls.

lhe points B C maybe connected at the base of the belfry, or to the masonry itself, or any other appropriate support. In this.latter case, the line B S C" would indicate this supportfthe form of which it is unnecessary-to describe, as it ma'yvary ad injfnitum, according to circumstances.

In saying that the three points A B U may be fixed at any part of' the plane perpendicular to the axis of the bell, I'intend to imply that these three point-s may be distanced, one from the oth'er7 as desired; but I do not wish it to be supposed that-they may be fixed otherwise than shown in the drawings, or below the horizontal line supposed to pass through the pivot o, as the principal' feature of the invention consists in always selecting the three points of suspension of the levers so that the lever A, which sustains the bell in repose, .should always have its point of suspension above the horizontal line above mentioned, and in the perpendicular which cuts the said line in the centre of the pivot o, and in order also that the levers B, and O should have their points of suspension always below the said horizontal line..

1n figs. 3 and 4, a belly is represented as suspended byl this system, the drawings showing a front and side view. The parts marked A serve to show the supports, or, in other words, the frame or substitute for the belfr'y. The piece of wood tB is a cross-beam, resting on the walls, to which the bell is hung, in this case, by means of the screws M.

All the pieces marked C form one solid piece,'which rests only in the turret ofthe belfry, on four points, like a table on its legs. The piece C is fixed to the parts A by means of four lateral screws. The fulcra of the levers 'B' C', destined to check the jerking of the bells, are obtained from this part C, which should be of' a sufficient weight to suit any bell that may be employed.

The two uprights D serve as' supports and fulcra to the small screws o, destined to check the movement of the axis of the bell from end to end. These screws have a plain surface.

The parts marked.l E are blade-shaped at their ends, and on these the levers rest, which, as represented in this drawing, are six in number. These pieces E are separated by six finger-nuts. Itis by distancing these pieces E, that the levers are fixed and regulated.

A B C are the levers. The pivots of the axis of the bell pass through apertures of the levers, and impart to them, in its movement, abackward and forward motion. The pivots are provided with rings, which separate the levers, and 4prevent their rubbing together.

These pivots turn in thel'bent and polished surfaces without, in any way, escaping, beingdrawn by the levers, in different manners, without any great friction, but simply that produced in rotating.

It is of importance that the points of suspension' should be iixed, as already described, as, in that case, no harm can happen to the beltry, should one be employed, as the swinging force acquired by the bell while in motion is checked by the levers'.

What I claim, and desire to secure by Letters Patent, is-

The system of suspended and oscillating levers for hanging bells, in the manner herein set forth, and illustrated by the accompanying drawings.

GILBERT EGUILLON.
